Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an information processing device that supports control between an operation device and a control target device via a network, an information processing device that operates as an operation device that controls the operation of the control target device, and an instruction from the operation device. The present invention relates to an information processing apparatus that operates as a control target device that executes processing, a control method thereof, and a program.
[0002]
[Prior art]
Web browsing for browsing content written in a markup language called HTML using a browser is now a technology that has become popular worldwide. HTML is a markup language for displaying content. HTML has a mechanism called a form, and can have GUI parts such as buttons and text boxes. With this and a mechanism called CGI (Common Gateway Interface) of the Web server, it means not only browsing but also a client (a computer and software using functions and data provided by the server in the network. This client. For example, a computer connected to a network, a home personal computer, and a Web browser or viewer operating on the computer). Can be executed, and the result can also be returned to the client in the form of HTML. For example, a Web search engine is generally realized by this method.
[0003]
This mechanism can be applied not only to Web browsing but also to device control. That is, a Web server is mounted on the control target device, and an HTML file including a form including a GUI component for controlling itself is transmitted to the operation device in response to a request from the operation device as a client. The operating device displays this HTML file on the browser, and the user operates the GUI on the operating device. The operating device transmits the input to a control target device (for example, a Web server). In the device to be controlled, this input is transferred to the control program by the CGI mechanism, and control according to the input is performed.
[0004]
On the other hand, in recent years, the form of information devices has been diversified, such as PDAs, mobile phones, car navigation systems and other portable terminals, and it has become possible to connect to the Internet from such devices other than personal computers (hereinafter referred to as PC). Yes. Along with this, markup languages replacing HTML such as WML have been developed and standardized. In addition, with the development of speech recognition / synthesis technology and the development of CTI technology, it becomes possible to access the Web by voice conversation via the telephone. With this, markup languages such as VoiceXML have been developed and standardized. Yes. Thus, a markup language suitable for a device form has been developed and standardized.
[0005]
In addition to diversification of device forms, UI modalities are diversified, such as GUIs for PCs and PDAs, and voice and DTMF for telephones. There is a growing interest in multimodal user interfaces that combine these diversified modalities to improve operability. The description of the multi-modal user interface includes a dialog description (description showing what input is received from the user, what output is made, and in what procedure the input / output proceeds) and a modality description (what UI components are included). At least a description indicating whether to use that input / output).
[0006]
The modality description is highly dependent on the client configuration. A general-purpose device such as a PC has abundant GUIs, and recently, some have a speech UI due to the development of speech recognition / synthesis technology. On the other hand, it is best to use voice for mobile phones. This is because a mobile phone supports a simple GUI component on a small liquid crystal screen, but does not have a pointing device and cannot always be said to be easy to use. In view of device control, there is a remote controller as an operation device. The remote control is generally operated by physical buttons.
[0007]
There are two kinds of methods for such dialog description and modality description.
[0008]
One is a method of clearly describing the modality input / output form in the dialog description, such as a certain input is a GUI button and a certain output is a voice. The other is a method of separating the dialog description and the modality description and describing the dialog description in a modality-independent manner.
[0009]
In the latter method, a dialog description, which is an operation procedure of a device to be controlled, is performed in a modality-independent manner, and in a form separated from this, for each client, a modality description adapted to the client is performed. , It becomes possible to operate one control target device from various clients. There is CML (Japanese Patent Laid-Open No. 2001-154852) as a markup language of a multimodal user interface capable of separately describing dialog description and modality description.
[0010]
In CML, the dialog description itself is described in a modality independent form, and there is no framework for performing the modality description itself and its control description. A modality is generated by converting the dialog description part into an existing markup language such as HTML, WML, VoiceXML or the like. Alternatively, when the browser directly executes CML, the browser is assumed to have a known modality of the mounted device, and the specification is left to the browser which modality is associated with which input / output element in the dialog description.
[0011]
Japanese Patent Laid-Open No. 2001-217850 separates input / output elements of a dialog description as a logical UI and each modality of a modality description as a concrete UI, and dynamically changes the concrete UI to a logical UI of a control target device according to a client. Proposes a way to connect.
[0012]
In the future, No-PC will progress, and it is expected that all types of devices will be equipped with CPUs and communication functions, and will cooperate with each other via a network to improve user convenience. From the UI point of view, it is not a dream to realize a device operating environment that does not select the type and location of devices, such as operating home appliances and vending machines instead of remote controls for mobile devices such as mobile phones and digital cameras. A Web mechanism based on the above markup language is effective in realizing such a device operating environment. Furthermore, a markup language that enables modality-independent description is effective for realizing a device operating environment where the type and location of the device are not selected.
[0013]
[Problems to be solved by the invention]
As described above, HTML, WML, VoiceXML, and the like, which are existing markup languages, are modality-dependent languages that assume an operating device form. Therefore, in order to enable control from various types of devices, the control target device must prepare a plurality of types of markup languages in accordance with the assumed operation device. In addition, HTML, WML, VoiceXML, and the like are not suitable for the realization of a multimodal user interface because operations that combine multiple modalities are not assumed.
[0014]
Also, although CML is a modality-independent markup language, the method of converting to an existing markup language such as HTML, WML, VoiceXML, etc. is not suitable for realizing a multimodal user interface as described above. On the other hand, when the browser directly executes CML, the browser is assumed to have a known modality of the installed device, and the specification is left to the browser which modality is associated with which input / output element in the dialog description. Therefore, the correspondence between the modality and the input / output elements is fixed, and there is no flexibility that can be controlled by the description of the markup language.
[0015]
Furthermore, Japanese Patent Laid-Open No. 2001-217850 provides a very simple connection between a logical UI and a concrete UI, for example, a logical UI of a type selected from options is connected to a concrete UI such as a radio button or a pull-down menu. Is doing. In this case, there is some restriction on the concrete UI that can be associated with the logical UI because it is not possible to associate a physical button with each selection item of the option or to select an item by repeatedly pressing one button. There is a problem of end.
[0016]
The present invention has been made to solve the above-described problems, and an object of the present invention is to provide an information processing apparatus capable of easily causing various devices to function as operation devices and control target devices, a control method therefor, and a program.

Before describing a specific operation example, a specification example of the multimodal user interface markup language (hereinafter referred to as MMML) of the present invention will be described.
[0055]
Three-layer structure
In the present invention, as shown in FIG. 8, the modality description depending on the device and the dialog description which is UI logic are described separately. In particular, in addition to a modality layer 801 indicating a modality description (portion enclosed by tags <modality> to </ modality>), an interaction layer 803 indicating an interaction description (portion enclosed by tags <dialog> to </ dialog>), It has a three-layer structure of a bind layer 802 that indicates a description (a portion enclosed by tags <Binds> to </ Binds>) that links a modality and a dialogue.
[0056]
Thus, by separating the modality description, it is possible to share one dialog description (UI logic) among a plurality of devices having different modalities. A specific example of this three-layer structure is shown in FIG.
[0057]
FIG. 8 shows the structure of a description (Mobile phone modalities) that can be operated from a mobile phone in addition to a copy machine modality description (Copier modalities) indicating the operation of the copy machine 101. As shown in this example, if one copier dialogue description (Copier Dialog) is configured, it is possible to perform operations from various devices only by describing a device-dependent modality layer and a bind layer for each device.
[0058]
Modality classes and instances
In the description of the modality layer in MMML, it is difficult to predefine all vocabularies representing modalities, that is, UI parts, as MMML definition words, and lack of extensibility. Therefore, several types of UI component classes that are expected to be generally used are defined as MMML common vocabulary, and a new class can be defined by inheriting this class. Furthermore, UI parts used in actual UI descriptions can be defined in the form of instances of such classes. In the first embodiment, an RDF schema is used as a method for describing class definition, inheritance, hierarchical relationships between classes, and instance definitions in XML. The RDF schema is a markup language (see http://www.w3.org/TR/rdf-schema/) that is standardized by the W3C (see http://www.w3c.org), a Web standards organization. It is.
[0059]
Generic modality class schema
Several types of GUI component classes that are expected to be commonly used are defined as MMML vocabulary in the form of an RDF schema. FIG. 9 shows an example in which this RDF schema (general-purpose modality schema) is schematically represented. As shown in FIG. 9, UI component classes can be defined hierarchically using the RDF schema. For example, “Button” can define “Physical Button” and “GUI Button” as subclasses. The former is, for example, a button of a copier, and the latter is, for example, a button displayed on a liquid crystal panel. Also, the XML representation of this RDF schema is as shown in FIGS. 19A to 19E.
[0060]
Modality schema of operation device (client)
Based on a general UI part class defined as an MMML common vocabulary, a schema that defines a UI part class and an instance dependent on an operation device is described. That is, this modality schema describes what modalities can be used in the operating device, and is assumed to be provided by the manufacturer of the operating device. For example, in contrast to the Generic Modalities Schema, a schematic example of a mobile phone modality schema corresponding to the mobile phone UI components (LCD, physical buttons, voice input, voice output, etc.) shown in FIG. As shown in FIG. The XML representation of this modality schema is as shown in FIGS. 20A and 20B.
[0061]
Dialogue layer
This is a layer for performing a specific dialog description, and a description independent of the modality is possible. In the MMML description, the dialog layer is described inside tags <dialog> to </ dialog>. The minimum unit of interaction is field (minimum interaction unit). The field has input / output elements such as input and output and an element called filled.
[0062]
Each of input and output is a tag that describes what information is input / output, and has an ID as an attribute. This ID is used when describing the binding with the modality described separately. This will be described later.
[0063]
Input element
Describe the type of input you want to accept in the field to which it belongs. The type of input is described in the type attribute. As attribute values, the following are pre-defined as MMML common vocabulary.
[0064]
"SelectMe"
This is a type of input that accepts the fact that there was an input. Modality such as “button” and voice can be bound.
[0065]
"SelectOne"
This is a type of input for selecting one of the options. For example, radio buttons and pull-down menus are typical modalities. The selectOne type input describes an option with an item tag. It is also possible to bind modalities such as “buttons” to each item.
[0066]
"SelectMany"
This is a type of input for selecting a plurality of options. For example, a combo box (ComboBox) is a typical modality. Like the selectOne type, the option is described with the item tag.
[0067]
"TextString"
This type of input accepts input of character strings. For example, GUI text boxes and voice input are typical modalities.
[0068]
Output element
Describes the output in the field to which it belongs. The output contents can be described with the content tag.
[0069]
filled element
Describes the action (action information) for the input in each field. There are various types of actions. This action includes interacting with an internal program other than the UI by script description or some description method (for example, receiving a “copy start” input and starting a processing program that actually performs copying). A typical action. Moreover, when responding to an input, an output tag can be described in filled.
[0070]
fields Role
Group fields. In general, UI logic is divided into several groups, and there are many cases where UI logic is defined in units of groups, so it is convenient to appropriately group fields (for example, the initial screen of a copier). And each setting mode).
[0071]
Example of a copier dialogue layer
FIG. 12 shows a description example of the interaction layer of the copy machine UI, and FIG. 21A and FIG. 21B show its XML representation.
[0072]
In this example, a UI for executing copy (CopyStart), paper selection (PaperSize), and single-sided / double-sided (PrintSides) is described. In this example, modality description, that is, what kind of UI parts to use, such as whether to input by buttons, voice, text display, or voice notification, is not used at all. Note that it is not described (modality independent).
[0073]
Bind layer
Since the modality-independent dialog description eliminates the modality, it is necessary to associate the modality with the dialog description. The binding layer is a layer that describes the association, and binds each modality defined in the modality layer to each input / output element in the interaction layer. The description of the association is performed by referring to the ID of the modality to be associated and the ID of the input / output element with a URI (Uniform Resource Identifier). The bind layer is described inside the tags <Binds> to </ Binds>. Each bind element is described inside tags <Binds> to </ Binds>. By binding a plurality of modalities to one input / output element of the interactive layer, it is possible to describe a multimodal UI using the selective use of multiple modalities and the cooperative use. In the bind layer, the following description about modality management is possible.
[0074]
・ Description of how to combine multiple modalities
・ Description of output contents
-Description of the activate / deactivate of the modality
Description of how to combine multiple modalities
When binding a plurality of modalities to one input / output element, it is possible to instruct how to combine modalities such as selective use and cooperative use. The combination instruction is described by the BindType attribute. As attribute values of the BindType attribute, the following are predefined as MMML common vocabulary.
[0075]
"Alt"
Any one of a plurality of modalities bound to input / output elements can be used. The priority of multiple modalities shall be in the order described. For example, when the radio button modality and voice input modality are bound with the “Alt” attribute to the input element that selects the paper of “A4 or B5” on the copier, this is the selection of the radio button or voice input. Either means that the paper can be selected.
[0076]
"Seq"
Apply multiple modalities bound to input / output elements in order. For example, it corresponds to an input such as “speak after pressing button A”.
[0077]
"Coordinated"
Coordinate multiple modalities bound to input / output elements. For example, it corresponds to an input of pointing “Osaka” on the displayed map with a pointing device while saying “From Tokyo to here”. The type of cooperative operation depends on the specifications of the browser that executes MMML, and is not defined in the present invention.
[0078]
Description of output contents
The output content can be described in the bind element that binds the output element of the interaction layer. The output contents may be written immediately inside the tags <Binds> to </ Binds>, or may be written inside each modality description to be bound. In this way, more appropriate output contents according to the modality can be described.
[0079]
For example, for a speech synthesis modality, a description is given that the message “Copy completed” is output, and for the notification sound playback modality, the file name of an audio file that sounds a “beep” is given. it can. As described above, the output content can also be described in the output element of the dialog layer (inside the tags <output> to </ output>). These priorities are
Inside modality description in bind element> Just inside bind element> Inside output element of dialog layer
It has become.
[0080]
Modality activate / deactivate Description
It is possible to activate / deactivate each bound modality. For example, it is possible to describe that the voice input modality is deactivated when the ambient noise is large. activate / deactivate is described by <activate modality = "..." /> tag and <deactivate modality = "..." /> tag, respectively.
[0081]
Binding layer example
For example, FIG. 13 shows an example of a binding layer that links the modality description (FIG. 11) of the mobile phone 102 and the dialog description (FIG. 12) of the copy machine in order to operate the copy machine 101 from the mobile phone 102. Further, the XML expression is as shown in FIG.
[0082]
In this way, in the present invention, the bind reasoning server 103 automatically generates this bind layer for any modality layer and any interaction layer, so that any operation device (for example, the mobile phone 102) can arbitrarily The control target device (copy machine 101) can be operated.
[0083]
Example of operating a copier from a mobile phone
An example in which a copier is operated from a mobile phone according to the markup language specifications as described above will be described.
[0084]
The mobile phone 102 holds a markup language having a modality layer as shown in FIG. This is normally created by the manufacturer of the mobile phone 102 and placed on the mobile phone at the time of shipment. On the other hand, the copier 101 holds a markup language having an interactive layer as shown in FIG. This is normally created by the manufacturer of the copy machine 101 and placed on the copy machine 101 at the time of shipment.
[0085]
The bind layer inference server 103 holds a bind sample as shown in FIG. 14, for example. This binding sample shows whether or not each generic modality defined in the schema of FIG. 9 can be bound to an input / output element, and appropriateness information indicating how appropriate the binding is (in the binding layer of FIG. 14). The number (value of 1 to 5) is the appropriateness, and the larger the number, the higher the appropriateness).
[0086]
For example, the modality “Button” can be bound to an input element of “selectMe” type with an appropriateness of 5, and can be further bound to each option (item) of an input element of the “selectOne” type with an appropriateness of 3. Show. The former is a correspondence such as “Copying starts when the start button of the copier is pressed”, and the latter is an option of “Tokyo”, “Osaka”, “Nagoya”. The association is “Osaka” when B is pressed and “Nagoya is selected when button C is pressed”.
[0087]
The modality “GUIRadioButton” indicates that it can be bound to the “selectOne” type input element with the appropriateness 5. Therefore, if the operating device has UI parts of both the “Button” class and the “GUIRadioButton” class, the appropriateness of the “selectOne” type input element is 5, so the modality of the “GUIRadioButton” class It would be more appropriate to bind.
[0088]
The bind layer inference server 103 binds the modality of the actual operation device and the input / output elements of the control target device based on such a bind sample. A specific example of the operation will be described in detail.
[0089]
FIG. 18 is a flowchart showing processing executed by the bind layer inference server according to the first embodiment of the present invention.
[0090]
First, when the user tries to operate the office copier 101 (control target device) with the mobile phone 102 (operating device) from outside, in step 101, first, the URL of the copier 101 and the mobile phone 102 Modality information including the modality layer (FIG. 11) is transmitted to the bind layer inference server 103.
[0091]
The bind layer inference server 103 receives modality information from the mobile phone 102 in step S201. Next, in step S202, a request for transmission of dialog information including a dialog description is issued to the copy machine 101 from the URL in the received modality information.
[0092]
Upon receiving this request from the bind reasoning server 103, the copier 101 transmits the dialog information regarding its own dialog layer (FIG. 12) to the bind reasoning server 103 in step S301.
[0093]
The bind layer inference server 103 receives the dialogue information from the copy machine 101 in step S203. Next, in step S204, the bind layer inference unit 1401 determines which modality of the mobile phone 102 should be bound to each input / output element of the dialog description in the dialog information. Specifically, with reference to the bind sample 1402 (FIG. 14), bind information including a bind layer that links the modality description of the mobile phone 102 and the dialog description of the copy machine 101 is generated as follows.
[0094]
For example, since the input element of the “CopyStart” field in the dialogue description of the copier 101 is of the “selectMe” type, the modality appropriate for binding to this from FIG. 14 may be the modality of the “Button” class. Understand. Also, from FIG. 9 and FIG. 11, among the modalities of the mobile phone 102, “10Key-0” to “10Key-9” of the numeric keypads (0 to 9) are instances as subclass instances of the “Button” class. I know that there is. Therefore, “10Key-0”, which is an appropriate one, is bound to the input element of “CopyStart” field.
[0095]
Similarly, since the input element of the “PaperSize” field is of the “selecOne” type, the “GUIRadioButton” class, the “GUICheckBox” class, the “SpeechInput” class are bound from FIG. 14, or the modality of the “Button” class is changed. You can see that you only need to bind to each option. From FIG. 9 and FIG. 11, among the modalities of the mobile phone 102, the voice input modality “MyASR” may be bound, or the numeric keys “10Key-0” to “10Key-9” may be bound to each option. I understand.
[0096]
Here, since “10Key-0” is already bound, “10Key-1” and “10Key-2” are bound to the choices “A4” and “B5”, respectively. This makes it possible to configure a multimodal interface that allows both voice input and button input by binding “MyASR”.
[0097]
Note that the recognition vocabulary of the voice input modality “MyASR” automatically generates “Ayeon” and “Vigo” from the choices. This can be done by reading from the descriptions “A4” and “B5” of the options by language analysis. Note that the reading process can be realized by a technique used in a technique such as speech synthesis, and the specific contents thereof are out of the scope of the present invention.
[0098]
The same applies to the input element of the “PrintSides” field, binding “10Key-3” and “10Key-4” to each option, and further binding the voice input modality “MyASR”. In this way, the bind information including the bind layer as shown in FIG. 13 is generated. In step S <b> 205, the bind layer inference server 103 combines the bind information including the bind layer and the dialog information including the dialog layer (FIG. 12) of the copier 101 and transmits the combined information to the mobile phone 102.
[0099]
As a result, the mobile phone 102 has a markup language in which its modality and the dialog description of the copy machine 101 are combined in the bind layer, and various operations of the copy machine 101 are executed based on this markup language. can do.
[0100]
Hereinafter, an operation example between the mobile phone 102 and the copy machine 101 will be described.
[0101]
After receiving the bind layer and the conversation layer from the bind reasoning server 103, for example, when the user presses the numeric keypad “1” of the mobile phone 102, the input / output management unit 1301 of the mobile phone 102 detects this. . By this detection, the modality management unit 1304 knows that there is an input via the modality “10Key-1”.
[0102]
The modality control unit 1305 refers to the bind layer description (FIG. 13) received from the bind layer inference server 103, and finds that this is bound to the input element option “A4” of the “PaperSize” field of the copier 101. Therefore, the fact is transmitted to the copier 101 via the communication unit 1306 as XML data as shown in FIG.
[0103]
The copier 101 receives the XML data of FIG. 15 via the communication unit 1203, interprets the content in the dialog execution unit 1201, and knows that the paper size is set to “A4”. Subsequently, when the user presses the numeric key “0”, the input / output management unit 1301 of the mobile phone 102 detects this, and the modality management unit 1304 knows that there is an input through the modality “10Key-0”.
[0104]
The modality control unit 1305 refers to the bind layer description (FIG. 13) received from the bind layer inference server 103 and knows that this is bound to the input element “CopyStart” field of the copier 101. The XML data as shown in FIG. 16 is transmitted to the copier 101 via the communication unit 1306.
[0105]
Then, the copier 101 receives the XML data in FIG. 16 via the communication unit 1203, interprets the content in the dialog execution unit 1201, and starts copying by the device control unit 1202.
[0106]
As described above, the bind layer inference server 103 binds the modality of the operation device (for example, the mobile phone 102) and the input / output elements in the dialog description of the control target device (for example, the copy machine 101). Even if the digital camera 106 is switched to the digital camera 106, the copier 101 can be controlled in the same manner as long as the digital camera 106 has its own modality description and functions similar to those shown in FIG. Further, even if the control target device is the air conditioner 105, it can be controlled in the same way as long as the air conditioner has the same function as that shown in FIG.
[0107]

A modality control unit that exchanges information with the input / output elements is configured. In addition, the control target device has a dialog execution unit that accepts input from each modality managed by the modality management unit and executes output instructions to each modality according to the content of the dialog description in the markup language. To do. Then, in accordance with the contents of the bind description in the markup language, a bind reasoning unit that passes information between the modalities and the input / output elements associated with each modality is configured in the bind reasoning server.
